@kenshirriff @cr1901 Undocumented pins: B06 & C07 E13 & F13 A04, B04, B12, C06

@cr1901 I've updated the schematics in the blog post. I'm not sure if it's worth staring at for an hour though :-) righto.com/2023/11/intel-…

First, the 386's clock pad received an external clock signal at twice the desired frequency. Two transistors were connected as diodes to clamp the signal if it was too high or too low, protecting the chip. 4/11

@aggarwal_pallav Yes. Industrial machinery and issues with ground destroy serial ports quite often.

Can this be a useful board for embedded engineers? ISOLATED USB to UART - USB-C to UART(3Mbps) - Power Isolated, capable of up to 200mA - Isolated RX, TX, RTS, CTS, DTR, DSR - Signal Voltage Level Selection 1.8/2.5/3.3/5V Your feedback/suggestions are welcome. Thank you

@JunesPhD General must-haves: DP832 power supply. MSO5000 scope. Fluke 87V DMM. Hakko FX888 soldering iron. Nice desk with overhead. Save the rest of the budget for projects or specialized specialized purposes (RF? SMD Rework station? Through-hole power electronics rework/desoldering?)

Now extrapolate this.

Holy cow. Everything you ever needed to learn about Makefiles, in one place. makefiletutorial.com

@halkyardo Maybe it's not actually quartz clocked? Many line-powered devices use the AC line frequency instead. Not saying it doesn't have quartz in there, but that it might be using it for something else (microcontroller, etc.) and not the actual time.

@DanielleFong This sums up my sentiment. twitter.com/atroyn/status/…

this is probably, the #1 reason that our impact on the world is so low per capita everyone wants there to be a person on the other side of their publishing, be it papers, or twitter, to take their idea and do the hard work of making something 🤷🏻‍♀️

Check out my functional art: ASA to ISO flange with no adapters edition. Eat your heart out vacuum hackers.

@tubechip404 Hi, A few of us are playing with Lattice ECP5 FPGAs at our local makerspace in Chicago and we were wondering if we could use multiple BPW34 PIN diodes and try to make something like this. We're working with the OSS-CAD suite and Verilog/LiteX and want to make an MCA.

3D Layout Patch. 🤣🤣🤣🤣

Did you know that contrary to popular belief, most volcano lairs lack luxuries such as 3-phase power, or even 220V supplies? Today, we rewire this vacuum pump to make do with the accommodations of a geothermal cavern.

I'm excited for the future.

@elonmusk Time for the "nutrition facts" of media corporations to be required labeling.

Canadian Broadcasting Corp said they’re “less than 70% government-funded”, so we corrected the label

@tubechip404 Would a 4 channel version using a single FPGA benefit at all from the scale?

Light up a chip. 😱

A sneak preview of OpenKayo, the project that's been consuming far too much time recently: an ESP32-based interface adaptor that turns a @kayosmt Kayo-A4 pick-and-place machine into a simple USB GCode device so it can be controlled by @openpnp

@tubechip404 Hi. I'm interesting in making something like this work with a CZT detector. Would these MCAs work just as well with this type of detector? Do you have any plans to either sell or open source these? I'd be happy to trade some CZT modules for MCA boards! Cheers!

Using this tiny digital multi-channel analyzer, the pulse shape discrimination function was successfully realized. (detector: NaI(Tl), source: Ra-226)

@Betavulgaris6 @MicrochipMakes I think the V is new 3.3V parts (which is the datasheet you are looking at). The ATF150xAS parts you mention are the 5V parts, though, they do have separate pins for Core and IO pwr. Technically, the pins for VccIO aren't documented for the ATF1502:Core and IO is same per sheet

Microchip's new ATF1504AS datasheet. But why not ATF1508AS and AT40K/AT94K etc.? @MicrochipMakes

Mad respect for those keeping the internet working during times of war. Mad respect for everyone who is working during these impossible times. I salute you, sir.

@rc3831 @jafuap @JoshWest247 @elonmusk I think as long as you don't have it upside down, you don't even have to point it -- it automatically positions upon powerup.

@jafuap @JoshWest247 @elonmusk Yes plug in and point to sky. Easy peasy.

#starlink for the win! No data blackouts. No censorship. @elonmusk
